Question

我在ajax调用下使用从服务器端获取json对象（php）

$.ajax({
    url: url,
    method: "POST",
    data: { cdrid : cdrid },
    dataType: "json",
    success: function(data)
    {
       $("#appName").val(data.appname);
       $("#callDate").val(data.callDate);
       $("#editHavenRecord").modal("show");                              
    },
    error: function()
    {  
       alert("Unable to get haven data");       
    }
});

我正在关注json对象作为来自服务器的响应

[{"id":"433","cdrid":"5339922","appid":"108","appname":"Haven Holidays(Service) 2009","dnis":"1172441753","CallDate":"2016-03-01","CallInTime":"2016-03-01 15:08:28","CallEndTime":"2016-03-01 15:11:25","TranscribeDateTime":"2016-03-02 05:16:56","agentid":"K9Q","calloutcome":"Good Record","TermCd":"GR","title":"Mr","fname":"Elwood","lname":"Ward","Addr1":"99 Enclingson Road","Addr2":"Bournemouth","Addr3":"","Country":"","city":"","town":"","postcode":"TH9 1HR","HeardAdvert":"BRAND_TV","ver_code":"VO","ver_date":"3\/2\/2016 5:26:32 AM","Duration":"177","HangUpCode":"8010","TranscribedBy":"Tom.Rodie   ","batchid":"903"}]

然而，当我尝试访问任何特定元素（如data.appname）时，当我尝试在控制台上打印任何元素时，它也不起作用，它给了我未定义的

data是一个包含一个元素的数组，它的元素就是你想要的对象。所以数据[0]

$.ajax({
        url: url,
        method: "POST",
        data: { cdrid : cdrid },
        dataType: "json",
        success: function(data)
        {
          

           // data is an array of one element inside, its element is the object you want. so data[0]
           $("#appName").val(data[0].appname);
           $("#callDate").val(data[0].callDate);
           $("#editHavenRecord").modal("show");                     
           
     
        },
        error: function()
        {
            
   
           alert("Unable to get haven data");
                
        }
    });
